Volume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D images from 3D volumetric data sets. Volume ray casting, which processes volume data, must not be mistaken with ray casting, which processes surface data.

Famous quotes containing the words volume, ray and/or casting:
“We are too civil to books. For a few golden sentences we will turn over and actually read a volume of four or five hundred pages.”
—Ralph Waldo Emerson (1803–1882)
“An original is a creation
motivated by desire.
Any reproduction of an original
is motivated by necessity ...
It is marvelous that we are
the only species that creates
gratuitous forms.
To create is divine, to reproduce
is human.”
—Man Ray (1890–1976)
“All we know
Is that we are a little early, that
Today has that special, lapidary
Todayness that the sunlight reproduces
Faithfully in casting twig-shadows on blithe
Sidewalks. No previous day would have been like this.”
—John Ashbery (b. 1927)
